MACHINE FOR BURNISHING THE EDGES OF SOLES.

SPECIFICATION forming part of Letters Patent No. 234,504, dated November 16, 1880.

Application filed October 6, 1880.

To all whom it may concern:

Be it known that we, BENJAMIN J TAY- MAN and JOSEPH BENNOR, both of Philadelphia, Pennsylvania, have invented an Improvement in Machines for Burnishing the Edges of Soles, of which the following is a specification.

This improvement consists in mechanism for impart-ing the required reciprocating mo- 1c tion to the tool in such a way that the carriage to which the tool is fast may change its relation to the eccentric-block, through which motion is communicated to the carriage from the driving-shaft, this mechanism consisting of a cylindrical eccentric-block having a cylindrical hole bored through it for the eccentric of the shaft, the block being in a cylindrical box formed in the tool-carriage. The eccentric part of the shaft, moving in a circle around the 2o axis ofthe shaft, throws the cylindrical block from side to side, and thereby reciprocates the cylindrical box in which the block moves up and down, and as that box is a part of the toolcarriage, that carriage is also reciprocated in its slides. The block being a cylinder, and its box being also cylindrical, the box can turn around the axis of the cylindrical block to an extent sufficient for all practical purposes while the machine is moving rapidly.

In the drawings, Figure l is a vertical section of the complete machine. Figs. 2, 3, 4, and 5 represent details on an enlarged scale. Fig. 6 is a side view, partly in section. Figs. 7 and S are details, illustrating the arrange- 3 5 ment of the cylindrical eccentric-block in the tool-carriage. Fig. 9 is a plan of the machine.

In the drawings, c represents a shaft with suitable bearings d e, and having in it an eccentric, j'. This eccentric ts a hole through the eccentric-block h, and this block is acylinder and fits in a cylindrical box formed in the tool-carrier i', the tool u being fast to fi, so that the motion of i shall give motion to the tool. The shaft cis revolved rapidly by the (Model.)

pulley g, and the eccentric j' reciprocates its block h and tool-carrier i.

Heretofore in these machines the eccentric` block was rectangular in cross-section and iitted in a box of the same shape in the tool-car- 5o rier, and consequently the tool-carrier could not be moved at all except forward and back.

In our machine this block is a cylinder, and its box is also cylindrical, so that the box can move within certain limits on the axis of the cylindrical block in either direction, and it is this which constitutes our invention.

The tool-carriert'is mounted in slides formed in the ring a', and both the tool-carrier t' and ring a are provided with apertures, so that 6o both can move within certain limits on the axis ofthe eccentric-block It, as shown in Figs.

1 and 7 and at a2 in Fig. 6. The tool-carrier is also secured to a by the shaft j, mounted in standards L and Z, fast to a', and this shaft j 65 carries the handle on.

The ring a is mounted in base a, which is fast to the socket b, which serves to connect the base a, with the arm of the machine. (Not shown, as it has been patented, the present in- 7o vention relating only to the means for reciprocatin g the burnishing-tool.)

The burnishing-iron u, Fig. l, the crescentshaped guard o, and its guide-bars, Figs. 1,2, and 3, are in construction similar to the like parts described and claimed in the said Letters Patent No. 162,206, except that the shaft p of the burnishing-iron is solid, while the like shaft described in the said patent is shown to be hollow, to admit of the introduction of gas- 8o pipe in to it.

q, Fig. l, is the gas-pipe, by which a flame of gas is directed on the exterior of the burnishing-iron a. The pipe q is supported by the bracket r.

The mechanism consisting of the cylindrical block h, eccentric f, shaft c, tool-,carrier t', and its support a may be used in combination for giving motion to a burnishing-tool for polishingpaperorfor other purposes. In this case 9o 2. In combination, shaft c, cylindrical eccentric-block h, tool-carrier z', ring af, shaft j, and base a, substantially as described.
